Modeling of a “HoloLens 1”-Type Layout with Light Guide Component
Abstract
Most innovative augmented and mixed reality devices nowadays are based on light-guide or wave-guide configurations in combination with microstructures to couple light in and out. VirtualLab Fusion is capable of the detailed modeling of such devices by applying our unique physical optics approach, which includes all effects of interest (e.g. coherence, polarization and diffraction). We demonstrate this capability by modeling a device of a simple “HoloLens 1”-type (1D-1D pupil expander) layout with a Light Guide component capable of guiding light with a 32° × 18° field of view.

Tutorial
Construction of a Light Guide
Light guides with coupling gratings can be set up in VirtualLab Fusion using the Light Guide component and its flexible region definition.
Use Case
Lightguide with Butterfly Eye-Pupil Expander based on Patent by Microsoft
This use case shows a lightguide system with a so-called “butterfly pupil expansion”, based on patent US9791703B1 by Microsoft.
Use Case
Lightguide with 2D-Periodic Grating Structures (Diamond-Shaped) Based on Patent by Wave Optics
In this use case we model a lightguide system that uses 2D-periodic grating structures (diamond-shaped), according to the approach from Patent WO2018/178626 (by Wave Optics LTD).
Use Case
MTF Analysis in Complex Waveguide Devices
In the field of AR/MR, the accurate calculation of the achievable optical performance is one of the major tasks in optical design.
